Nuxt UI v4
Component library for Vue 3 and Nuxt 4+ built on Reka UI (headless) + Tailwind CSS v4 + Tailwind Variants.
Current stable version: v4.3.0 (December 2025)
When to Use
- Installing/configuring @nuxt/ui
- Using UI components (Button, Card, Table, Form, etc.)
- Customizing theme (colors, variants, CSS variables)
- Building forms with validation
- Using overlays (Modal, Toast, CommandPalette)
- Working with composables (useToast, useOverlay)
For Vue component patterns: use vue skill
For Nuxt routing/server: use nuxt skill

Usage Pattern
Load based on context:
- Installing Nuxt UI? → references/installation.md
- Customizing theme? → references/theming.md
- Component index → references/components.md
- Specific component → components/button.md, components/modal.md, etc.
- Building forms? → references/forms.md
- Using overlays? → references/overlays.md
- Using composables? → references/composables.md
DO NOT read all files at once. Load based on context.
